Ghost Trap

So the Proton Pack was done...but I wasn't..so I had to build a Ghost Trap...the Proton Pack does me no good if I can't trap the free roaming vapors right?!?! The trap doors electronically open and there is a light show (it's really cool!!! but the room needs to be pretty dark to really appreciate this feature) The picture I used as the current "thumb" picture is after the doors have shut, the yellow lights at the front of the trap are going through their sequence and the red light at the back of the trap will start blinking. Wanted to somehow use dry ice to simulate the steam after a ghost is trapped, but thought better of it for fear it would ruin the electronics and/or the motor that controls the doors.
